Zynga said Tuesday that its chief financial officer, David Wehner, has departed for a job at Facebook and announced another reshuffling of its top-ranking executives.

Mark Vranesh, until now the gaming company's chief accounting officer, replaced Wehner as the new top financial executive, a position that he previously held.

Zynga's mobile chief David Ko was named the chief operation officer; vice president of corporate development Barry Cottle was tapped as chief revenue officer, and Steven Chiang, former executive vice president of games, became the president of games.

"I have greatly enjoyed working closely with [founder and CEO] Mark Pincus and the rest of the team," Wehner said in a statement. "The time I spent at Zynga has been an exciting chapter in my career as we led the rapid development of social gaming."

The leadership change is the latest in a series of top-level shakeups, which included the loss of marketing, revenue and creative officers.

Last month, the company laid off more than 150 employees in Austin and Boston, and the latter studio was completely shuttered.
